2025 Community Space Weather Modeling and Data Assimilation Workshop

This year's event will be held on September 10-11, 2025 at the UCAR Foothills Lab campus in Boulder, Colorado.

Objectives:

• Exchange technical knowledge and details on ongoing space weather modeling and data assimilation efforts
• Gather key stakeholders involved in developing community and advanced data assimilation systems within the JEDI framework for ionosphere-thermosphere-mesosphere (ITM) space weather forecasting models.
• Collect operational needs for developing community space weather modeling and data assimilation systems
• Assess the roles and contributions of each participant and explore how resources can be effectively shared to achieve common objectives.

Topics of interest for presentations include (but not limited to):  

• Current operational capabilities and plans
• Advances in modeling and coupling efforts
• Observations and measurements, including commercial vendors
• Advancement in data assimilation: algorithm, configurations, impacts
• Model and observation biases and uncertainty (error) estimation
• Post-processing methods to improve space weather forecasts
• Machine learning development and applications
